Precision DC Bench Power Supply – 0–30V 0–3A with OVP/OCP Alarms & USB

AU$212.70Price
Excluding Sales Tax
Compact precision DC bench power supply with 0–30V adjustable output up to 3A, featuring over-voltage (OVP) and over-current (OCP) alarm protection, low-ripple output, high-resolution digital display, and integrated USB fast-charging ports. Ideal for laboratories, electronics R&D, education, repair, and testing applications.

This precision DC bench power supply is designed to deliver stable, accurate, and low-noise DC power for professional and educational environments. Supporting constant voltage (CV) operation with controlled current limiting, it is well suited for electronics development, PCB debugging, laboratory experiments, and equipment servicing.

The unit includes user-selectable over-voltage and over-current protection. When abnormal conditions such as over-voltage, over-current, or short circuits are detected, the power supply automatically disables the output and triggers an audible alarm, protecting both the connected load and the power supply itself.

A bright 4-digit LED display provides clear, real-time voltage and current readouts with fine resolution, even in low-light conditions. The output ON/OFF control allows voltage and current to be preset safely before energising the terminals, reducing accidental damage during setup.

The compact vertical bench design saves workspace while remaining lightweight and portable. Integrated USB-A and USB-C fast-charging outputs provide convenient auxiliary power for development boards, test devices, phones, and tablets. An intelligent temperature-controlled cooling fan ensures quiet operation under light loads and effective thermal management during extended use.
